I still have my doubts whether the puzzle car really is a Ghia bodied one. The rear fender line is not like those of the Fregate Ghia Cabriolets I have seen pictures of. It resembles rather the fender line of the Chapron or Letourneur et Marchand cabriolets, but it is different to those in the way the A-post meets the body (Chapron) or the upper door line (Letourneur et Marchand). Further on, all Ghia Fregates I know have a sloping upper door line the puzzle car has not. So far I haven't found a picture of a Fregate Cabriolet which fits with the puzzle car.
